Help for duplicate photo and video scanning, on-device AI verification, large-video review, Recently Deleted cleanup, and PhotoDeDupe Pro purchases.
Email lnguyen@plnguyen.com for help with PhotoDeDupe.
To speed up troubleshooting, include:
Open Settings → Detection sensitivity. Strict only matches near-identical images, Balanced is the default, and Loose catches edits, crops, and burst shots. Try Balanced or Loose if you suspect duplicates were missed.
The first scan computes fingerprints for every photo and stores them locally so future scans are much faster. Pro adds Vision verification and quality ranking, which is also cached. Keep the app open and the device awake during the first scan.
Free users get a limited number of full scans before the AI features lock. If you used them already, open the Pro upgrade screen to subscribe or buy lifetime access, or restore purchases if you already paid.
iOS moves deleted photos to the Recently Deleted album for 30 days. To reclaim storage now, open Photos → Albums → Recently Deleted, then Select → Delete All. The in-app banner after a delete provides a one-tap shortcut to Photos.
Use Restore Purchases inside PhotoDeDupe and confirm you are signed in to the Apple ID that made the original purchase. If the issue continues, email support with the product you bought and your device details.
iOS schedules background processing tasks based on device usage and charging state. The app requests a scan every few hours, but iOS decides when to run it. Foreground scans from the Home screen are always available.
Tapping Don't Allow on the iOS Photos delete prompt is treated as a cancel and not an error. The app suppresses these cancellations silently. If you see a real error message, please share it with support.
Settings → About → Reset fingerprint cache deletes all cached image fingerprints. The next scan will take longer because every photo will be hashed again. Use this only if duplicate results look incorrect.
Payments, subscription renewals, cancellations, and refunds are handled by Apple. For refunds, use Report a Problem.
If Pro access does not unlock correctly after a successful purchase, use Restore Purchases first before contacting support.
